Juniper Networks, a provider of secure AI-driven networks has announced that together with Vodafone, a provider of Open Radio Access Network (RAN) solutions and Parallel Wireless, an Open RAN vendor fostering open interfaces have achieved a field trial. This will validate both admission control and traffic steering applications are running on top of the open and interoperable Juniper RAN Intelligent Controller (RIC) platform.’
This trial, validated with live traffic on a Vodafone commercial network, is based on an open, software-driven architecture that demonstrates the power of openness and intelligence to effectively address the key business challenges faced by mobile operators today OPEX control, service differentiation, customer experience and sustainability, among others.
The Admission Control use case combines both the rApp and xApp from Juniper, allowing real-time tracking and optimisation of radio resources such as User Equipment (UEs)/tenant and Power Distribution Unit (PDUs)/tenant based on current traffic utilisation. The application allows for the dynamic allocation of network resources without the need for over-provisioning all the way to specific customers, therefore improving resource management and network efficiency. As a result, operators can achieve cost savings with streamlined operations and reduced equipment needs while providing a higher quality of service to end users.
The Traffic Steering xApp from Parallel Wireless, in conjunction with Juniper’s rApp, enhances the user experience by dynamically and automatically distributing network load. Based on the traffic/cell conditions in Vodafone’s live network, throughput improvements of 40% were observed for users that were experiencing low performance due to cell overload, and an average of 15% to 30% improvement was observed across all users in the overloaded cell. This application efficiently utilises operator resources to meet capacity demands without requiring manual intervention, thereby helping to reduce costs and to minimise errors.
Both use cases demonstrate that user experience can be managed and optimised automatically by the RIC, based on real-time data insights. These use cases can be implemented uniformly across RANs in a multi-vendor environment. The ability to deploy innovative applications from third-party vendors on top of the Juniper RIC platform helps mobile operators and third-party apps unlock the full potential and benefits of Open RAN.
Sustainable networking is imperative for mobile operators, and RIC trials in Open RAN networks such as this one will help drive more energy-efficient and sustainable operations. RIC applications such as Admission Control can lower RAN energy consumption by avoiding over-provisioning of resources to handle peak traffic. Likewise, the Traffic Steering application allows efficient utilisation of network resources to meet capacity demands while avoiding additional capital investments. These applications can also lower the overall RAN energy consumption, contributing to the achievement of mobile operators’ sustainability targets.
Vodafone and Juniper Networks will embark on the next phase of collaboration on the Radio Intelligence Controller with the development of advanced use cases such as energy saving and mMIMO optimisation. The collaboration will also involve validating third-party rApp/xApp vendors using SDK and APIs exposed by the Juniper RIC.
All three organisations are active operators/contributors of the O-RAN Alliance and the Telecom Infra Project (TIP), underlining their shared commitment to industry innovation and standards.
“At Vodafone, we have a clear vision that Open RAN will transform networks into open platforms for innovation. The success of this trial represents the first RIC deployment in our live commercial network, aligned with the O-RAN Alliance specifications. We were pleased to come together with our partners, Juniper Networks and Parallel Wireless, to validate the performance of third-party app integration, demonstrating the power of openness and intelligence. There is tremendous potential in the RIC space outside of traditional use cases, and this represents only the beginning of demonstrating the full potential of Open RAN.” says Paco Martin, head of Open RAN at Vodafone Group.
“We are thrilled to collaborate with an Open RAN providers like Vodafone contribute to the potential that this trial represents for mobile operators and customers alike. This trial is a testament to the clear focus on open interfaces and multi-vendor interoperability that the Juniper carrier-grade RIC platform represents. The trial serves as a significant stepping stone that will spur further innovation in the Open RAN space.” says Constantine Polychronopoulos, Group VP, 5G & Telco Cloud at Juniper Networks
